Optical Frequency Measurement by Conventional Frequency Multiplication

Measurements of several stable optical frequencies using the PTB frequency chain are reported. The measurement scheme together with the ingredients (radiation sources, nonlinear elements, coherence) for such measurements are discussed. A comparison of different frequency chains is reported and the measurements planned for the near future are mentioned.
It is generally hoped that a high (e.g. optical) frequency atomic quantum transition can improve the accuracy of future frequency standards over those presently available, which are based upon microwave transitions. This is suggested by the fact that the homogeneous linewidth of an atomic transition the quantity with the largest influence on the accuracy of a standard, is largely independent of the transition frequency.
